Array Antenna power splitter

Hi all

im making a 8 element linear array at 9.5GHz and i have made a simple 3dB power splitter for a 2 element array and i was wondering if the graphs are ok both the S21 and S31 are around 3dB however in the smith chart it is not around the middle...so i was wondering was that ok

can someone please help me

yes, it should be about 3.5dB for S21 and S31. You can try to add some match stub to adjust the output impedance.
